CPC counter-pressure casting mold trial-test implements the strictest industrial acceptance standards, focusing on high-pressure stability, ultra-low defects and high-precision forming performance.
CPC mold trial-test includes 4 high-pressure closed-loop test batches, all operated under 0.1–0.15MPa constant counter-pressure working environment.
Qualified CPC trial castings require porosity shrinkage below 0.5%, achieving the highest quality level in aluminum alloy casting industry.
High-pressure sealing performance is the primary test item, requiring zero pressure leakage and 100% pressure holding stability during full filling cycles.
Dense cooling channel operation verification ensures 10–16mm spacing temperature balance, with overall mold temperature difference controlled within 25℃.
Procast CAE simulation for CPC trial verification requires 1 million+ grid units, with simulation and actual test error strictly below 3%.
Cavity precision detection maintains ±0.025mm tolerance, verifying high-precision forming capability for high-end aluminum castings.
H13 steel pressure resistance test completes 600 continuous high-pressure cycles, requiring no deformation or fatigue crack generation.
High-end aluminum wheel mold and high-load EV structural part mold must pass full CPC high-pressure trial-test before delivery.
Trial-test verifies sequential feeding effect under counter pressure, eliminating loose structure and internal micro-shrinkage defects completely.
All CPC trial-test data is archived as official quality certification documents for high-end customer factory inspection and product certification.
CPC counter-pressure casting mold trial-test is the most rigorous quality verification procedure in the aluminum mold industry, tailored for high-precision, high-strength and ultra-low-defect casting scenarios. Different from conventional LPDC and gravity mold tests, CPC trial-test takes high-pressure sealing stability as the core inspection standard, because counter-pressure filling and feeding are the core advantages of CPC technology. Four rounds of closed-loop high-pressure tests fully simulate formal mass production working conditions, eliminating hidden dangers such as pressure leakage and unstable feeding. Ultra-low porosity acceptance standards ensure the compactness and mechanical properties of high-end aluminum wheels and new energy vehicle structural parts. High-precision cavity detection and temperature balance verification guarantee long-term dimensional stability of precision castings. Professional high-precision Procast CAE simulation matches actual test data with extremely low error, proving the scientificity of mold structural design. Strict cycle fatigue testing of H13 hot-work steel ensures that the mold can withstand long-term high-pressure and high-temperature alternating loads. Complete data archiving and certification system make CPC molds meet the quality access standards of global high-end casting manufacturers.
